Ghaslakh Crusade
The Ghaslakh Crusade was a planned Crusade of the Ultramarines during the Great Crusade, focused against Orks on Ghaslakh. However the Crusade, ordered by the now-traitorous Horus, was part of a ploy to have the Ultramarines ambushed by the Word Bearers. Much of the forces intended for the Crusade instead became bogged down in the Battle of Calth.[1]
